ANTIFRICTION-BEARING FOR AXLES.

Specification of Letters Patent.

Patented Nov. 18, 1915.

Original application filed October 28, 1909', Serial No. 525.200.Divided and this application filed January 42,

To all whom it may concern:

Be it known that we, VVILLARD C. LIFE and HARRY D. WEED, of Syracuse, inthe county of Onondaga and State of New York, have invented a certainnew and useful Antifriction-Bearing for Axles, of which the following isa specification.

This invention relates to antifriction bearings for axles, and has forits object a particularly simple and efficient journal bearingstructure; and the invention consists in the novel combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings, in which like characters designate corresponding parts in allthe views.

Figure 1 is a sectional view, partly in elevation, of this bearing,contiguous parts of the axle and truck frame being also shown. Fig. 2 isan end view thereof, the outer end wall being removed. Fig. 3 is adetail View of a portion of the journal box, two of the rollers beingalso shown. Fig. 41 is a fragmentary detail view of the opposing ends ofthe transversely split bearing ring and the coacting expanding member.

This bearing comprises generally a journal boX having an annularraceway, the circumferential wall of which is provided with a detachablebearing ring, and means for expanding the ring to hold the same inposition in the raceway.- Preferably, the ring is transversely split andthe means for expanding the ring acts as a wedge to separate the ends ofthe ring, and includes a member carried by the box substantiallyradially with the axis of the raceway and having a tapered head coactingwith the opposing ends of the ring. We have here shown this bearing ringas embodied in an antifriction bearing for axles, such as shown in ourpending application, Sr. No. 525,200, filed October 28, 1909, of. whichapplication this is a division.

1 is the journal box provided with an axle receiving opening-'2through'one end wall thereof and having its opposite end closed, saidopening 2 having adjacent its opposite ends concentric annular raceways3 spaced apart from each other, and each formed with opposing fiat sidesor surfaces disposed at right angles to the axis of the bearing.Preferably, theraceways 3 are substantially cylindrical, are of greaterdiameter than the Serial No. 341.

lntervening portion of the axle opening and are connected by an oilpassage 4 extending parallel to the axis of the opening 2 through theportion of the wall of the journal box between the bottoms of theraceways.

In the bearing here illustrated, the ournal box 1s provided withexternal projecting portions 5 into which the race-ways extend, and isalso provided between the planes of the raceways 3 with externallyarranged and vertical channels 6 confinedbetween said projectingportions 5 and adapted to receive parts as jaws 7 of the truck frame.

Preferably, the journal box is provided with detachable endwalls ordisks 8, 9, re spectively, secured to the main body or intermediate partof the journal box by any suitable fastening means as screws 10, 11,these end walls having their opposing faces provided with flat surfacesforming sides of the raceways, and said end walls, when removed,permitting access to the interior of the journal box. The removable endwall 8 is provided with an axle opening forming a continuation of theopening 2, and may be provided with any suitable means for preventingthe entrance of dust to the interior of the journal box, as a packingring 12 arranged in an annular channel 13 in the outer face of the endwall 8, and a clamping sleeve 14 having an annular member movableaxially into said channel against the packing ring 12, the clampingsleeve being provided with a flange 15 which is clamped by screws 16turning into the end wall 8. The outer removable end wall 9 supportsmeans for adjusting the bearing endwise' and for resisting the endthrust of the axle, said means comprising generally, a cylindrical plug17 screwing Within a central opening 18 in the end Wall 9 and formedwith an internal chamber 19 opening through its inner end in alinementwith the opening 2, a pair of disks 20', 21, located in said chamber androtatable independently of each other upon a pin 22 extending axiallythrough the-disks and antifri'ction members between the disks. The innerdisk 20 projects beyond the inner end of the plug 17 in position toengage the end of the axle, and an annular series of antifriction balls23 are arranged concentric with the pin 22 between the disks and roll ingrooves in said disks. A coiled spring 24 is arranged in a pocket in theouter end of the plug 17 and bears against the disk 21 for causing thedisk 20 to engage the end of the axle 25 on which the journal box ismounted.

Each raceway 3 contains a series of cylindrical rollers 26 arrangedparallel to the axis of the opening 2. The portion of the bearingbetween the walls or disks 8, 9, that is, the intermediate part of thebearing is formed at its ends with flanges constituting the end walls ofthe channels 6 and the circumferential and inner side walls of theraceways 3, and the end flanges of said intermediate part are detachablysecured by bolts 10, 1-1,'to the outer portions of said walls, or disks8, 9. The raceways are of greater diameter than the axle opening and areof greater diameter than the distance between the external channels 6 inwhich the jaws of the truck frame are located, as described in ourpending application referred to. I

27 designates the split ring located in each raceway 3 and engaging thecircumferential wall thereof, and also abutting against the opposingside walls of said raceway. 28 is the expanding member having a taperedhead 29 engaging opposing ends of the split ring.

As here shown, the ring is formed with a tapered perforation formedpartly in each of the margins at its opposing ends, the beveled walls ofthe perforation converging outwardly or radially, and the expandingmember 28 extends radially with the axis of the raceway, and has itstapered or beveled head located in said perforation 30. Said member 28is here shown as a screw or bolt on the outer end of which a nut 31turns against the outer face of the journal box, as seen in Fig. 3. Theexpander 28 is arranged on the lower side of the raceway so'that therollers when running over the ends of the ring are not supporting theload, and the.

head of the expander 28 is arranged with its upper face below thesurface of the ring on which the rollers run. The rollers in theraceways preferably do not run directly upon the axle, but upon a sleeve32 on said axle.

The ring 27 is formed of harder material than the journal box andprovides a convenient and economical way for forming the raceways withhard circumferential running surfaces which can be easily removed andreplaced.
